Hi Luciano,<br>
<br>
I did a few tweaks. Instead of TextColor dominating any Shout
Attribute, I made TextStyle normal do that. Additionally, the final
$. is added without any attribute, so whatever follows it is back to
normal. Just pushed it to github.<br>
<br>
Thanks,<br>

<div>Hi Juan,</div>
<div>Here are the changes. I've been using it like this for a

continue using it like this, unless we come up with other
better ideas.</div>
<div>Still I've been experiencing some problems, sometimes
underscores are not converted to arrows, and sometimes the

messy so there might be other reasons.</div>

<div bgcolor="#ffffff"> My previous answer is
completely wrong, because I conflated two issues
you raised.<br>
<br>
Your solution works well to avoid styling the
result of a printIt as if it was Smalltalk code.
But it doesn't address the other issue you raised,
that is, after that point, the styling of the rest
of the workspace is messed up.<br>
<br>
My suggestion (modifying #printIt to enclose the
result in double quotes) actually addresses both
issues: comments are not styled, and smalltalk
code after them is styled correctly. Maybe we'd
push this instead? Perhaps we'd also tweak the
style so it doesn't look like comments, but the
main point is that parsing will be correct
afterward. We could also add a dot after the
comment, maybe that makes Shout happier in case
you forgot to type it.<br>
<br>
The real fix would be to shout from scratch after
2 empty lines. That was the intended behavior some
time ago, and it works for coloring but not for
assignment arrows. Fixing this is a bit more
complicated. so I'd sugges opening an issue on
GitHub so we don't forget.<br>
<br>
Thanks,</div>

I guess this
should be
fixable. If you
can prepare an
image with such
example for me
to play with,
I'll give it a
try. For example
(not sure if
related)
VectorEngine can
do blending over
translucent
backgrounds, but
only if subpixel
sampling is
used. I know,
there is no
relation between
these two
features... But
I wanted to keep
options to a
small number,
and usually we
only use cheaper
whole pixel AA
and cheaper
alpha blending
that can't blend
over translucent
backgrounds. So,
maybe just using
the SubPixel
engine solves
this problem, or
I'll be happy to
take a look.<br>
